The memory stores the values of any
number of journeys, until it counts a

●
Only use the tool supplied with the vehicle

bolts.
● Loosen the wheel bolts only about one turn
before r
aising the vehicle with the jack. ●
If the wheel bo
lt is very tight, you may be
able to loosen it by pushing down on the end
of the wheel brace carefully with your foot.
Hold on to the vehicle for support and take
care not to slip.
Loosening wheel bolts
● Fit the wheel brace as far as it will go over

g anti-theft wheel bolts
For wheels with full hubcap, the anti-theft
wheel lock must be threaded into position
››› Fig. 54 2 before mounting the hubcap.
Other w
i

se it will not be possible to mount the
entire hubcap.
● Take the adapter for anti-theft wheel bolts
out of the
vehicle tool kit.
● Insert the adapter onto the wheel bolt
›››
Fig. 54. Push it on as far as it will go.
● Fit the wheel brace onto the adapter as far
as po
ssible.
● Hold the wheel brace at the end and rotate
the bolt ap
proximately one turn anticlockwise
››› .Important information about wheel bolts
The wheel
rims and bo

lts have been de-
signed to be fitted to factory options. If differ-
ent rims are fitted, the correct wheel bolts
with the right length and correctly shaped
bolt heads must be used. This ensures that
wheels are fitted securely and that the brake
system functions correctly.
In some circumstances, wheel bolts from the
same model vehicle should not be used.
Wheel bolt tightening torque
The prescribed tightening torque for wheel
bolts for steel and alloy wheels is 110 Nm.
Have the tightening torque of the wheel bolts
checked as soon as possible with a reliable
torque wrench.
If wheel bolts are rusty and it is difficult to
tighten them, the threads should be replaced
and cleaned before checking the tightening
torque.
Never grease or lubricate wheel bolts or the
wheel hub threads. Although they have been
tightened to the prescribed torque, they
could come loose while driving. WARNING
If the wheel bolts are not fitted correctly they
cou l

d be released while driving leading to
loss of vehicle control and serious damage. 38

The essentials
Tyres with compulsory direction of ro-
t ation A directional tread pattern can be identified
by
the arr
ows on the sidewall that point in
the direction of rotation. Always observe the
direction of rotation indicated when fitting
the wheel to guarantee optimum properties
of this type of tyres with regard to grip,
noises, wear and aquaplaning.
If it is absolutely necessary to fit the spare
tyre* against the direction of rotation, drive
with care as this means the tyre does not of-
fer optimum driving properties. This is of par-
ticular importance when the road surface is
wet.
To return to directional tread tires, replace
the punctured tyre as soon as possible and
restore the obligatory direction of rotation of
all tyres.
After the wheel change ●
Clean the vehicle tools, if necessary and
p ut
them a

way in the luggage compartment
foam holder ›››
 page 70.
● Store the spare wheel, the temporary spare
wheel or the ch
anged wheel securely in the
luggage compartment. ●
Have the tightenin
g torque of the wheel
bolts checked as soon as possible with a tor-
que wrench ››› page 38.
● Have the flat tyre replaced as quickly as
poss
ible.
Snow chains Use When using snow chains, applicable local
l
e
gi

slation and maximum permitted speed
limits must be observed.
In winter weather, snow chains not only help
to improve grip but also improve the braking
capacity.
The fitting of chains is permitted only on
front wheels and with the following combi-
nations of wheel trims and tyres :
Tyre sizeWheel rim
165/70 R145 J x 14 offset of 35175/65 R14 SEAT recommends you ask a technical serv-
ic
e f
or f

urther information on wheel, tyre and
chain sizes.
Wherever possible use fine-link chains meas-
uring less than 15 mm including the lock. Remove wheel hub covers and trim rings be-
fore fittin

g snow chains ››› . The wheel bolts
shou l
d be c
overed with caps for safety rea-
sons. These are available from technical serv-
ices.
Temporary spare wheel
For technical reasons, snow chains must not
be used on the compact temporary spare
wheel ›››
 page 206.
If it is necessary to fit chains with the tempo-
rary spare wheel in use, install the wheel on
the rear axle in the event of a fault in a front
wheel. Then, fit the rear wheel that is free, in-
stead of the damaged front wheel. In this sit-
uation, observe the rotating direction of the
wheels. SEAT recommends attaching the
snow chains before fitting the wheel. WARNING
The use of unsuitable or incorrectly fitted
ch ain

s could lead to serious accidents and
damage.
● Always the appropriate snow chains.
● Observe the fitting instructions provided by
the snow c
hain manufacturer.
● Never exceed the maximum permitted
speeds
when driving with snow chains. » 41
